ASE A7 Test Prep – Heating and A/C - Questions, Answers and Explanations Technician A says that the pressure cycling switch is usually located on the accumulator. Technician B says that the refrigerant must be recovered from the system before the switch can be removed. Who is right? A. Technician A only B. Technician B only C. Both A and B D. Neither A or B The pressure cycling switch senses the low-side pressure near the evaporator outlet and is usually found on the accumulator. Technician B ...

Fluid pushed thru a semipermeable membrane - Ultrafiltration Known as solute drag, solute move w/ water across the semipermeable membrane. *kidneys remove waste this way* - Convection Movement of dissolved particles across a semipermeable membrane from *high* to *low* concentration - Diffusion Fluid move from *low* to *high* solute concentration - Osmosis 1) Fluid Balance (ultrafiltration) 2) Electrolyte balance (diffusion) 3) Acid/Base balance - Kidneys excretory functions 1) Renin (an...

In the water, the level of exercise is a function of what FIVE factors? correct answers (1) Speed of movements; (2) Rate of change in speed (acceleration); (3) Surface area (frontal resistance) in the direction of the motion; (4) The participant's and the water's inertia; and (5) The number of times you change direction How is motion in the aquatic environment affected by the water's viscosity? correct answers Water is more viscous than air. The friction between molecules in water is w...

Viscosity correct answers Refers to the friction between molecules of a liquid or gas, causing the molecules to tend to adhere to each other (cohesion) and in water to a submerged body (adhesion). How is motion in the aquatic environment affected by the water's viscosity? correct answers Water is more viscous than air. This friction between molecules, or water's friction, is what causes resistance to motion when exercising. A combination of the surface area of an object and its speed determ...

1. Skin friction i. Viscous drag in the bound- ary layer ii. Friction of the fluid (air) against the object's "skin" (auto body) 2. Form Drag i. Caused by pressure differ- ential in front of/behind ve- hicle as viewed by the air stream. ii. Keys for reducing: con- tinuous streamlines, avoiding flow separation. 3. Contributors to drag Forebody, Afterbody, Under- body, Skin friction, wheels and wheel wells, drip rails, window recesses, external mirrors, etc. 4. Pressure Distribution ...

For a given weight airplane, the angle of climb depends on the difference between thrust and Power. Drag. Weight. Available airspeed. - ️️Drag Your review of the weight and balance of your airplane shows an aft C.G. but within limits. You should brief your crew to expect: a. Higher stall speed, higher cruise speed, and less stability. b. Lower stall speed, higher cruise speed, and more maneuverability. c. Lower stall speed, lower cruise speed, and less controllability. d. High...
